Considering that a good number of pictures of the alleged super plane were hoaxes, I find no reason to believe it actually exists.
I think the existence of the plane or any enabling technology is fodder for the credulous.
We’ve had anti-gravity technology since 1956. It was invented by Daniel Dunn, who later pioneered the homework machine. I thought everybody knew that.
You missed that Air Force General Leroy Brown was put in charge of Area 51 decades ago.
The Case of The Anti-Aging Serum was actually part of a disinformation campaign.
I came in here to say the same thing: all aircraft are anti-gravity flying machines.
Gravity is very easy to overcome.
Only in a very temporary sense.
What goes up must come down.
The lead story for your source is
(bad punctuation and random capitalization theirs)
Next time cite something a little less ridiculous…like Fate magazine.
'Nuff said.
Looks at username
When I jump, the Earth follows.
For fun, just remember that the OP was/is a science teacher.
If you want to see less than fully explained anti gravity phenomenon, especially with triangle shaped craft that are real then look up lifters, or the beaufield-brown effect , or brown effect lifters.
Reality is stranger than fiction.
Oh my!
It’s pretty cool. Not even remotely useful, but cool.
I have a hard time believing these claims, since the Weekly World News hasn’t reported on it yet.
Urbanredneck, meet Jim B.
Which is an interesting engineering proposition, but they’ll publicly roll it out when they are good and ready to do so. If they decide to go on with it at all. Heck, we’re all still waiting for the Aurora, aren’t we?
I expect that for every weapons system/platform actually presented in society as it were, there are a dozen proposals and prototypes that nobody outside the design bureau and the services’ advanced projects units ever lays eyes upon because not worth the cost or testing shows it is not really ready for prime time or the intelligence people tell you the other guys have already figured out a counter anyway.
Ah yes biefield…it’s been 20 years and I didn’t bother to look it up just now.
And yeah basically impractical for any use currently since no power source is light enough to produce the power needed to lift itself using the effect.
Is the full name the TR-3B Photoshop?
Google “escape velocity” and prepare for a surprise! 
I’m surprised that you’re not deferring to Flyer in this area 
If Cecil were still writing columns, surely the title of this thread would be included in a “QUESTIONS WE’RE STILL THINKING ABOUT” addendum.
examples here:
Oh, I guess it does see some use in the novelty that is bladeless fans, or moving the air in electrostatic filters.
